The shorter the time between generations the faster that speciation can occur. However, it is more common for the process to be extended over many generations (up to millions; Coyne & Orr 1997, 2004).The process is continuous, but it may be helpful to ask what initiates the evolution of intrinsic reproduction isolation, what causes isolation to increase (in terms of both . Diversifying selection can also occur when environmental changes favor individuals on either end of the phenotypic spectrum. The biggest factor is with the rate of creating offspring.

Boggs, in International Encyclopedia of the Social & Behavioral Sciences, 2001 3.2 Parapatric Speciation 'Parapatric' derives from 'para' meaning 'near' and 'patria' meaning 'country.' Parapatric speciation thus occurs when a smaller population is isolated, usually at the periphery of a larger group, and becomes differentiated to the point of becoming a new species. Although several mechanisms have been proposed to explain how speciation occurs, allopatric, parapatric, peripatric, and sympatric speciation have been considered to be the basic modes of speciation. (see, Hybridization is known to happen between what are generally accepted to be different species sometimes this leads to new species, other times some traits from one species become incorporated into another species. The concluding synthesis question asks to explore how reproductive isolation differs for each mode. That is, they won't exchange genes with one another even if the geographical barrier is removed.
